PATENT FFICE.

LILLIAN M. DABNEY, OF ROSEDALE, KANSAS.

VACUUM WASHER.

Application filed August 6, 1923. Serial No. 655,882.

To all whom it may concern:

Be it known that I, LiLLIAN M. DABNEY,

a citizen of the United States, residing at Rosedalc, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Vacuum lVashers, of which the following is a specification. lifliy invention relates to improvements in vacuum washers, such as are employed in washing garments and fabrics of different descriptions, and an important feature of the invention resides in mechanism for automatically lifting said vacuum washer after the same has been pushed downwardly to force water through the articles being washed.

In vacuum washers of this character which are pushed downwardly by hand to force the water through the articles being washed, a partial vacuum is created at each downward stroke which renders it somewhat difficult to raise the device on each upward stroke, but by providing the device with my invention said device is automatically lifted and thus relieves the operator of this portion of the work.

In order that the invention may be fully understood reference will now be had to the accompanying drawing, in which 1 is a vertical central section of the washer equipped with my invention.

Fig. 2 is an inverted plan view.

The washer consists of a conical. vacuum cup and a handle 4. The handle, in the present instance, consists of a tubular shank 6 fixed at its lower end to the upper end of the cup 2 and provided at its upper end with a knob 8, which overlaps said shank 6 and presents a broad bearing surface for the hand of the operator.

10 designates a solid guide fixed in the upper portion of the conical cup 2 above a partition 12 to guide a plunger 14 and reinforce the upper portion of said cup 2. The partition 12 holds the guide 10 in place and coacts therewith in reinforcing the cup 2. The plunger 14 extends through a central hole 16 in the guide 10 and is provided at its lower end with a cushion 18 to protect the article being washed from damage by the plunger. The upper end of the plunger 14 is provided with a fixedly mounted disk 20 having an upturned marginal flange 22 for retaining in position the lower end of a coil spring 24, the upper end of which embraces and is held in position by the reduced lower terminal 26 of the knob 8.

Normally the spring 24 holds the plunger 14- in its lowermost position, but when the washer is pushed downwardly to the dotted line position, Fig. 1, by pressure on the knob 8, the coil spring 24 is compressed and lifts the washer on its upward stroke when the knob 8 is relieved of downward pressure, thereby relieving the operator of the labor of overcoming the partial vacuum which is created each time the washer is pushed downwardly to force water through the articles being washed. As the washer is pushed downwardly as stated, it is guided by the guide 10 and the disk 20.

From the foregoing description, it is apparent that I have produced a device embodying the advantages above pointed out, and while I have shown and described the preferred construction, combination and arrangement of parts, I reserve the right to make such changes as properly fall within the spirit and scope of the claim.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is: i

A device of the character described CO11- sisting of a conical vacuum cup, a tubular shank fixed to the upper end of said vacuum cup, a knob fixed to the upper end of said shank and having an upper portion overlapping said shank, a solid plunger extend ing axially through said vacuum cup and into the shank, a solid conical guide having a central bore for the passage of said plunger and fixed in the vacuum cup to reinforce the same, a cushion fixed to the lower end of said plunger, a disk fixed to the upper end of said plunger, and a coil spring seated at its ends against said disk and the knob, substantially as shown and described.

In testimony whereof I afiix my signature.

LILLIAN M. DABNEY.
